The H20, H10, H5, and E5 are magnetic field (H) and electric field (E) probes for radiated emissions EMC pre-compliance measurements. The probes are used in the near field of sources of electromagnetic radiation. They serve to locate and identify potential sources of interference within the building blocks of electronic assemblies. The probes act similar to wide bandwidth antennas, picking up radiated emissions from components, PCB traces, housing openings or gaps, and from any other parts that could be emitting RF. The probes are usually connected to a spectrum analyzer. Scanning the probe over the surface of a PCB assembly or housing quickly identifies locations that emit electromagnetic radiation. By changing to a probe with a smaller size, the origination of the emissions can be further narrowed down.
The ESD-Sense has been developed with EMC test laboratories in mind to enable a “go / no-go” verification of the ESD generator output prior to test.
